Abstract

La presente describe técnicas para mejorar decisiones de seleccion de modo durante la codificacion de macro bloques (u otros bloques) de cuadros de multimedia de una secuencia de multimedia. Durante la estimacion de movimiento, los modos de codificacion para macro bloques se puede determinar de manera que se puede lograr una velocidad de codificacion deseable y nivel de distorsion aceptable (es decir, velocidad de distorsion aceptable). Las técnicas pueden incluir seleccionar un conjunto de modos de codificacion de multimedia entre al menos dos conjuntos de modo de codificacion de multimedia posibles para un macro bloque y un cuadro de multimedia basado en una métrica detallada asociada con el macro bloque e informacion de modo asociada con bloques vecinos al macro bloque.This describes techniques for improving mode selection decisions during the coding of macro blocks (or other blocks) of multimedia frames of a multimedia sequence. During motion estimation, the coding modes for macro blocks can be determined so that a desirable coding rate and acceptable distortion level (i.e. acceptable distortion rate) can be achieved. Techniques may include selecting a set of multimedia coding modes from at least two possible multimedia coding mode sets for a macro block and a multimedia box based on a detailed metric associated with the macro block and information associated with neighboring blocks to the macro block.
